Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application entitled “Hybridized Cable Assembly,” which was filed on Nov. 13, 2017, and assigned Ser. No. 62/585,292, the contents of which are herein incorporated by reference in their entirety.

FIELD OF THE DISCLOSURE

The present disclosure relates to cable assemblies (e.g., hybridized cable assemblies) and, more particularly to the design and use of hybridized cable assemblies configured to facilitate the transfer of data and power.

BACKGROUND OF THE DISCLOSURE

Traditionally, copper cables have been utilized for transferring data and power over some distance. However, copper cables can be affected by electromagnetic interference (“EMI”) and further may not provide the necessary bandwidth over desired distances. Therefore, some active optical cables, utilizing fiber cables, have been developed to attempt to provide an upgrade over the traditional copper cable. However, some current active optical cable products, such as, RapidRun® Optical and Chromis Fiberoptics, are generally limited to data transfer only and typically require power to be added separately. This can result in additional wiring, increased labor costs, and the potential for interferences.
Based on the foregoing, a need exists for the combined transfer of data and power without substantial interference. Thus, an interest exists for improved cable assemblies, and related methods of use. These and other inefficiencies and opportunities for improvement are addressed and/or overcome by the assemblies, systems and methods of the present disclosure.

Referring now to the drawings, like parts are marked throughout the specification and drawings with the same reference numerals, respectively. Drawing figures are not necessarily to scale and in certain views, parts may have been exaggerated for purposes of clarity.
FIG. 1 depicts an exemplary hybridized cable assembly 10 that is configured and adapted to transfer data and power across a length of hybridized cable assembly 10. In an exemplary embodiment, the hybridized cable assembly 10 includes an active optical cable (“AOC”) 12 that further includes a copper portion 24 or the like, and a fiber portion 26 or the like, combined and/or incorporated therein (FIG. 2).
Copper portion 24 (or a material of similar functional qualities) is configured and adapted to transfer power from a first end 11 of hybridized cable assembly 10 to a second end 13. Fiber portion 26 (or a material with similar functional qualities) is configured and adapted to transfer data from first end 11 of hybridized cable assembly 10 to the second end 13. In some embodiments, the hybridized cable assembly 10 is bi-directional, with copper portion 24 also configured and adapted to transfer power from second end 13 to first end 11, and with fiber portion 26 also configured and adapted to transfer data from second end 13 to first end 11.
As shown in FIG. 1, hybridized cable assembly 10 further includes at least one printed circuit board (“PCB”) 16 that is electrically connected to AOC 12. In an exemplary embodiment, assembly 10 includes two PCBs 16 electrically connected with AOC 12, with a first PCB 16 at first end 11 within first housing 15, and a second PCB at second end 13 within second housing 15. In general, each PCB 16 electrically and longitudinally bridges one end of AOC 12 to connector 14, e.g., RJ-45 plug/jack connector 14. However, other connectors can be incorporated without departing from the scope of this disclosure, e.g., HDMI, USB, as desired.
In some embodiments, each PCB 16 can be permanently attached to AOC 12 and semi-permanently attached to connector 14, wherein each PCB 16 and connector 14 are detachable from one another.
In other embodiments and as shown in FIG. 6, each PCB 16 of hybridized cable assembly 300 can be permanently attached to connector 14 (e.g., via cable 17) and semi-permanently attached to AOC 12, wherein each PCB 16 and AOC 12 are detachable from one another. Cable 17 can be a network cable 17 or the like.
It is to be appreciated that AOC 12 of FIG. 6 can extend to a second end 13 of assembly 300, and second end 13 of assembly 300 can include second connector 14 attached proximal to second end 13 of AOC 12 (e.g., via plugs 118, 122), and can include second housing 20 and second PCB 16 proximal to second end 13. In other embodiments, end 13 of AOC 12 of FIG. 6 can be hardwired directly into a device or the like. In other embodiments, it is noted that connector 14 of FIG. 6 can take the form of RJ-45 plug connector 102 or the like of FIG. 4.
Referring back to FIGS. 1 and 6, to protect each PCB 16, a plug 18, 118 and a cover 20, when combined together, form PCB housing 15, which encapsulates and/or houses PCB 16.
Exemplary plug 18, 118 includes a slot 19 that interfaces with a portion of PCB 16 to assist in performing a stable electrical connection with connector 14 and/or AOC 12. The slot 19 can include retention features to constrain PCB 16 from rotational or longitudinal movement. In an exemplary embodiment, PCB 16 includes a spade-like electrical connection that connects with connector 14 and a portion of said spade-like connection is retained by the slot 19. Plug 18 can be a cylindrical feature that interfaces with mating plug 22 on connector 14. Plugs 18, 22 can further include retention features to securely and releasably attach connector 14 and plug 18 to one another.
In another embodiment and as shown in FIG. 6, plug 118 of housing 15 is configured and dimensioned to interface with mating plug 122 on AOC 12 (e.g., on first end 11 of AOC 12 and/or on second end 13 of AOC 12). Plugs 118, 122 can further include retention features to securely and releasably attach AOC 12 and plug 118 to one another (e.g., via mating plug 122).
Exemplary cover 20 is a hollow feature or member (e.g., cylindrical, rectangular, polygonal, etc. feature or member 20), with a first opening 21 (e.g., large opening 21) that interfaces with plug 18, 118, and a second opening 23 (e.g., smaller opening 23), opposite the first opening 21, that interfaces with AOC 12 (FIG. 1), or interfaces with cable 17 of connector 14 (FIG. 6).
In some embodiments and as shown in FIG. 1, the second (smaller) opening 23 is slightly larger than the outside diameter of AOC 12 (or cable 17 of FIG. 6) to enable cover 20 to slide along AOC 12 to allow for easy access to PCB 16 (or to slide along cable 17 of FIG. 6 to allow for easy access to PCB 16).
Although plugs 18, 22, and cover 20 are depicted as cylindrical features in FIG. 1, the design is not limited to such and can include, for example, other shapes/sizes (e.g., rectangular, polygonal, triangular, elliptical, quadrilateral, etc.; see cover 20 of FIG. 6).
Plug 18, 118 and/or cover 20 can further include electromagnetic (“EM”) shielding to reduce the electromagnetic field. Such materials for EM shielding can include, but are not limited to, sheet metal, metal screen, metal foam, metallic ink. Although AOC 12, PCB 16 and connector 14 are depicted as being assembled longitudinally, each can be assembled at least perpendicularly or the like with respect to the adjacent component.
Functionally, when input connector 14 (e.g., proximal first end 11) receives the incoming combined transmission, e.g., data and power, provided by the Power over Ethernet (PoE), connector 14 will split or separate the data and power and feed the respective separate transmissions to the attached PCB 16 for further processing. Once the separate data and power have reached the other end of hybridized cable assembly 10, output connector 14 (e.g., proximal second end 13) will recombine the signal and power into an outgoing combined transmission, thereby providing bi-directional communication. Although the term input connector 14 and output connector 14 are used to describe the bi-directional communication process, no specific connector 14 is solely considered the input or the output, either connector 14 can be the input or the output (e.g., connector 14 proximal to end 11 or 13 can be input connector 14; connector 14 proximal to end 11 or 13 can be output connector 14).
Each exemplary PCB 16 is configured and adapted to perform an optical/electrical conversion. In a two PCB 16 assembly, either PCB 16 or both can perform this conversion. PCB 16 will receive and transmit data from the optical fiber(s) 26 and also receive and transmit power provided by PoE over the copper wire(s) 24. Each PCB 16 can include circuitry to step up or step down (e.g., modify) the voltage in the copper wire(s) 24.
Each PCB 16 can also include circuitry to scrub the power signal to remove external radio frequency (“RF”) interference. PCB 16 can further provide a media access control address (“MAC address”) to the end equipment/device depending on the application, e.g., if AOC 12 was replacing an optical network terminal (“ONT”) in a passive optical LAN (“POL”) application.
FIG. 2 depicts an exemplary active optical cable (“AOC”) 12 which includes at least one copper cable 24 and at least one fiber cable 26, combined and/or incorporated therein. As shown in FIG. 2, AOC 12 can include two copper cables 24 and two fiber cables 26.
In exemplary embodiments, each copper cable 24 and each fiber cable 26 runs the length of AOC 12 from first end 11 to second end 13 and provide the means for transferring power and data, respectively. It is noted that the internal fiber of fiber cable 26 can be glass optical fiber or plastic optical fiber (POF). POF can allow for easy field termination, if desired by a user. Furthermore, the fiber cable 26 can include a pair of fibers, a ribbon of multiple pairs of fibers, or a functionally similar design.
Copper cable 24 may include a twisted pair or straight, and may further include electromagnetic (“EM”) shielding. Copper cable 24 can be large enough in diameter to support the power requirements for POE applications. The exemplary cables 24, 26 are insulated in a protective coating/shield to ensure the cables 24, 26 remain isolated from each other. Furthermore, by limiting the data to only pass through the fiber cable 26 and not the copper cable 24, interference of the data will be significantly reduced or even substantially eliminated. Although AOC 12 is depicted with a circular cross-section, AOC can also be arranged in a ribbon, or can include other shapes/forms or cross-sections.
FIG. 3 depicts fully assembled hybridized cable assembly 10 as was described with reference to FIG. 1. Although hybridized cable assembly 10 depicts two RJ-45 jack connectors 14 and two PCB housings 15, hybridized cable assembly 10 can function with only one of each.
In some applications where one end of AOC 12 is hardwired directly into a device, only one set of PCB housing 15 and connector 14 is required. Functionally, the bandwidth of data transferred over some distance is a function of the construction of the PCB and AOC 12.
In one example, bandwidths exceeding about 100 gigabytes can be achieved at distances of about 100 meters. In another example, data can be transferred with a bandwidth of about 10 gigabytes over a distance exceeding about 300 meters. These examples are not meant to be limiting of the potential bandwidth or distance that is achievable, they are merely exemplary and assist those persons skilled in the art to make and use the hybridized cable assemblies of the present disclosure.
In another embodiment, FIG. 4 depicts fully assembled hybridized cable assembly 100. Hybridized cable assembly 100 is substantially similar to hybridized cable assembly 10, as illustrated in FIGS. 1 and 3, however, the assembly 100 includes two RJ-45 plug connectors 102. Hybridized cable assembly 100 functions similar to hybridized cable assembly 10 and such explanation can be referenced to assist those persons skilled in the art to make and use hybridized cable assembly 100.
In another embodiment, FIGS. 5A and 5B depict a fully assembled hybridized cable assembly 200. Hybridized cable assembly 200 includes one RJ-45 jack connector 14 and one RJ-45 plug connector 102. Hybridized cable assembly 200 functions similar to hybridized cable assembly 10 and such explanation can be referenced to assist those persons skilled in the art to make and use hybridized cable assembly 200. It is noted that there could also be an application where a fiber duplex pair is directly plugged into one jack side and converted to RJ-45 on the opposite end of the link with POE added at the RJ-45 side.
There are many applications for assembly 10, 100, 200 and/or 300. Such exemplary applications include, without limitation, new building design, consumer home applications, internet of things (JOT), replacement for high bandwidth copper applications (e.g., CAT 8 and higher), and they may be used in SNAP applications or the like.
There are many benefits or advantages for utilizing assembly 10, 100, 200 and/or 300. Such exemplary advantages include, without limitation, high bandwidth (e.g., about 40 to about 100 Gig possible depending on construction of the PCB 16 and cable 12); uses POE; can function with available hardware (e.g., RJ-45 connection); reduces/eliminates interference (e.g., Alien Cross talk); cable 12 can be run in the same pathways as existing power lines (reduced install cost); easier handling and installation than fiber alone; can support power/data for IOT devices; in a POL application one may be able to replace the ONT; cable diameter can be reduced compared to copper cable; data can be transferred with higher bandwidth over longer distances than copper (e.g., CAT 8 limitations) (greater than 30 m, 100 to 300 meter lengths possible); if POF is used, field termination can be simple.
Although the systems and methods of the present disclosure have been described with reference to exemplary embodiments thereof, the present disclosure is not limited to such exemplary embodiments and/or implementations. Rather, the systems and methods of the present disclosure are susceptible to many implementations and applications, as will be readily apparent to persons skilled in the art from the disclosure hereof. The present disclosure expressly encompasses such modifications, enhancements and/or variations of the disclosed embodiments. Since many changes could be made in the above construction and many widely different embodiments of this disclosure could be made without departing from the scope thereof, it is intended that all matter contained in the drawings and specification shall be interpreted as illustrative and not in a limiting sense. Additional modifications, changes, and substitutions are intended in the foregoing disclosure.
